PSA: Do not use "Reported-By" without reporter's approval

[Konstantin Ryabitsev <konstantin@linuxfoundation.org>]

Hello, all:

It is common courtesy to include this tagline when submitting patches: 

Reported-By: J. Doe <jdoe@example.com>

Please ask the reporter's permission before doing so (even if they'd 
submitted a public bugzilla report or sent a report to the mailing 
list). They need to understand and agree that:

- their name and email address will become a permanent, non-excisable 
  part of the Linux Kernel git history
- their name and email address will be stored on multiple public 
  archival copies of the linux kernel mailing list, collected and 
  managed by different legal entities

With or without GDPR laws, this is something the reporter needs to be 
aware of and they need to be okay with it, as a matter of courtesy.
